Atmel
microcontroller was based on the classic 8051 core. The on-chip Flash memory retained its
contents even after power was turned off, and was electrically erasable and
programmable. Atmel 8051 8-bit microcontrollers were the industry’s first Flash based
microcontrollers featuring In-System Programming. Atmel was again the first to develop the
In-Application Programming feature in its Flash microcontrollers thereby enabling remote
upgrades.
Now Atmel is writing a new chapter in 8051 history with its AT89LP series of next
generation 8051 microcontrollers that offer higher performance and lower power than
classic 8051s, plus easy migration and greater levels of system integration. The Atmel
AT89LP family is based on a low-power, high-performance 8-bit single-cycle 8051 Core
that is 100% binary compatible with the traditional 8051 instruction set and yet provides 6
to 12 times more throughput. AT89LP microcontrollers are optimized for low power and
high performance applications. The AT89LP microcontrollers reduce system cost and
enable faster time-to-market by providing such features as: In-Application Programmable
